UNITRONIC® BUS AS-I (G)

(Farnell: Unitronic BUS AS-I (G)

Application

UNITRONIC® BUS AS-I (G) is a field-bus cable 3G3G-FI 2 x 1.5 with 2 cores for AS-INTERFACE (Actuator- Sensor

Interface). Networking system for the lower field area.

The data transmission for AS-Interface telegrams and power supply for AS-Interface slaves, master,

repeater, extender and sensors is done via this unscreened, geometrically-coded two-core flat cable. Contacting the

conductors without stripping the insulation by insulation-displacement-system of AS-I modules.

The cable is intended for fixed and flexible installation in interiors.
